Title: Spatial digitizer
Inventor: KIELLAND PETER JOHANN
IPC: G06F3/0346
Filed: 1999-05-17
Abstract: A handheld pointer-member, freely moveable within an orthogonally referenced three-dimensional workspace. Six rotational encoder assemblies, electronically couples to a host computer, are axed in pairs to form a triangle. Six tensioned cables are guided through six holes near each of the six rotational encoder assemblies. Each cable contacts an encoder's rotateable input shaft, thereby digitizing all changes in the cable's extended length into the host computer. One cable from each vertex of the triangle is affixed to one of two cable attachment points spaced apart on the pointer-member. The host computer continuously trilaterates the XYZ locations of both cable attachment-points using measured changes in the six cable lengths. The pitch and yaw attitude between the two cable attachment points is derived and used to compute the locations of the tips of the pointer-member. The user guides the pointer-member's tips over an object's surface, thereby digitizing its shape into the host computer.

Title: Gps multipath detection method and system
Inventor: SCHIPPER BRIAN W
IPC: G01S1/00
Filed: 1997-11-20
Abstract: A multipath detection method for use in a GPS position determination system includes providing a code pseudorange measurement representative of a range of an antenna to a space vehicle and a carrier phase pseudorange measurement representative of the range of the antenna to the space vehicle. A code-carrier measurement difference is then generated between the code pseudorange measurement and the carrier phase pseudorange measurement. This code-carrier measurement difference is examined to determine if a multipath component is present. If the difference indicates that multipath is likely to be present, use of such measurements in computing position solutions, such as attitude solutions, is avoided. A multipath detection system for carrying out the method is also described.

Title: Slurry hydrocarbon synthesis process with multistage catalyst rejuvenation
Inventor: COULALOGLOU CONSTANTINE A
IPC: B01J8/22
Filed: 1998-04-29
Abstract: A reversibly deactivated hydrocarbon synthesis catalyst in a hydrocarbon synthesis slurry is rejuvenated by successively passing the slurry through at least two rejuvenation stages external of the slurry reactor, each of which comprises a rejuvenation zone followed by an offgas removal zone. This is accomplished by using a lift pipe outside the reactor into which slurry from the reactor is passed and contacts a catalyst rejuvenating gas to partially rejuvenate the catalyst particles and form a rejuvenation offgas. The gas and slurry mixture are passed into a vessel in which the gas is removed from the slurry. Rejuvenation gas is bubbled into the slurry in the vessel to further rejuvenate the catalyst. A gas removing downcomer removes gas from the slurry in the vessel before it is passed back into the reactor.      The rejuvenation gas also acts as a lift gas in the lift pipe.

Filed: 1998-04-20
Abstract: A novel injector/reactor apparatus and an efficient process for the partial oxidation of light hydrocarbon gases, such as methane, to convert such gases to useful synthesis gas for recovery and/or subsequent hydrocarbon synthesis.  Sources of a light hydrocarbon gas, such as methane, and oxygen or an oxygen-containing gas are preheated and pressurized and injected through an injector means at high velocity into admixture with each other in the desired proportions, at a plurality of mixing nozzles which are open to the catalytic partial oxidation reaction zone of a reactor and are uniformly-spaced over the face of the injector, to form a reactant gaseous premix having a pressure drop through the injector. The gaseous premix is injected in a time period which is less than 5 milliseconds, at a velocity between about 25 to 1000 feet/second, into a reaction zone comprising a catalytic partial oxidation zone so that the gaseous premix reacts in the presence of the fixed catalyst arrangement to reduce the amounts of CO2, H2O and heat produced by the partial oxidation reaction and form, cool and recover a useful syngas.

Title: A system and method for detecting and locating heart disease
Inventor: LIU HAI XIANG
IPC: A61B5/308
Filed: 1999-02-19
Abstract: A method is delineated for detecting, locating coronary artery, and heart disease comprising the steps of obtaining electrocardiograph signals from a patient, modifying the EKG signals, and establishing a base value for use in evaluating modified EKG signals. The step of modifying includes the steps of amplifying (14) the EKG signals, digitizing amplified EKG signals, mathematically modifying the amplified, the digitized EKG signals to obtain twelve lead signals in the time domain, and converting the twelve lead signals into power spectrum signals in the frequency domain. The base value is obtained by taking a patient's resting heart rate in beats per minute, converting it to beats per second, multiplying it by a scaling quantity between approximately three, and seven, inclusively. A system (10) corresponding to the aforementioned methodology is also shown.

Title: Improved method of melting solid materials
Inventor: HANSEN JAMES E
IPC: B09B3/00
Filed: 1998-06-08
Abstract: A method of melting solid materials while controlling melt shape, without the expenditure of energy to melt unwanted quantities of surrounding materials, and an apparatus to effect the method.      The method comprises the use of a planar starter path (48) between the electrodes (40) so as to initiate melting and/or vitrification in a plane rather than in a discrete linear path between the electrodes (40). Because melting is initiated along a significant portion of the linear dimension of the electrodes (40), creating a melted zone that is deeper than it is thick, the aspect ratio (depth "Y"/width "Z") of the melted mass (138) is greater than 1Ø

Filed: 2000-02-15
Abstract: A system, device, and method for interfacing multiple protocol stacks in a communication network utilizes a virtual circuit subsystem to interconnect protocol stacks internally within a network device. The victual circuit subsystem establishes a virtual connection between at least a first protocol of a first protocol stack and a second protocol of a second protocol stack. The virtual circuit subsystem enables messages to be exchanged between the first protocol of the first protocol stack and the second protocol of the second protocol stack over the virtual connection. Specifically, the virtual circuit subsystem converts a transmitted message received from the first protocol into a received message for the second protocol, and converts a transmitted message received from the second protocol into a received message for the first protocol.
Patent CA-2300130-A1 (CA)
Title: An embedded dct-based still image coding algorithm
Inventor: CHRISTOPOULOS CHARILAOS
IPC: H04N7/30
Filed: 1998-06-05
Abstract: In an embedded DCT-based (EDCT) image coding method, decoded images which give better PSNR over earlier JPEG and DCT-based coders are obtained by a scanning order starting, for each bitplane, from the upper left corner of a DCT block (corresponding to the DC coefficient) and transmitting the coefficients in an order of importance. An embedded bit-stream is produced by the encoder. The decoder can cut the bit-stream at any point and therefore reconstruct an image at a lower bitrate. The quality of the reconstructed image at this lower rate is the same as if the image was coded directly at that rate. Near lossless reconstruction of the image is possible, up to the accuracy of the DCT coefficients. The algorithm is very useful in various applications, like WWW, fast browsing of databases, medical imaging, etc.
